Several criteria are used for determining the acceptability of whole cottonseed (WCS) for crushing including concentrations of moisture, oil, free fatty acids in the oil (FFA), and ammonia. Whole cottonseed that does not meet the minimum standard is typically sold as a feed ingredient. When tropical storms delay cotton harvest and the moisture remain elevated, concentrations of FFA increase. Fe...

We evaluated the validity of using a single fatty acid tracer to assess total plasma long-chain free fatty acid (FFA) kinetics and the relationship between the rate of appearance (R(a)) of fatty acids in plasma and the fatty acid composition of adipose tissue triglyceride (TG). A mixture of [(13)C]-labeled myristate, palmitate, stearate, oleate, and linoleate was infused in healthy men during b...

In a previous study the oxidation of plasma free fatty acids (FFA) under baseline conditions and during exercise was lower in type 2 diabetic subjects compared with weight-matched controls. The present study intended to investigate the effect of weight reduction (very low calorie diet) on plasma FFA oxidation in seven type 2 diabetic male subjects (body fat, 37.4 +/- 1.2%; age, 51.3 +/- 3.4 yr;...

Epididymal-fat-pad adipose tissue obtained from obese-hyperglycemic mice exhibited an impairment in its ability to mobilize free fatty acids (FFA) when incubated with epinephrine and in response to a 16-hour fast. Unexpectedly, FFA production by adipose tissue of fed obese mice was significantly greater than that observed in adipose tissue obtained from lean littermates. It is suggested that...

Microbial synthesis of free fatty acids (FFA) is a promising strategy for converting renewable sugars to advanced biofuels and oleochemicals. Unfortunately, FFA production negatively impacts membrane integrity and cell viability in Escherichia coli, the dominant host in which FFA production has been studied. These negative effects provide a selective pressure against FFA production that could l...

The aim of this study was to evaluate the effect of proteolytic (Serratia liquefaciens, match %: 99.39) or lipolytic (Acinetobacter genomospecies 10, match %: 99.90) psychrotrophic bacteria (bacterial counts, analysis of free fatty acids (FFA) and analysis of free amino acids) on the microbial and chemical properties (yogurt composition), and sodium dodecyl sulfate polyacrylamide gel electropho...

The periparturient period of dairy cows is characterized by intense lipolysis in adipose tissues (AT), which induces the release of free fatty acids (FFA) into circulation. Among FFA, polyunsaturated fatty acids are susceptible to oxidation and can modulate inflammatory responses during lipolysis within AT. Linoleic and arachidonic acid oxidized products (oxylipids) such as hydroxy-octadecadien...

It has previously been demonstrated (1) that in the postabsorptive state energy production of the heart depends largely on fatty acid metabolism; both esterified and nonesterified or free fatty acids (FFA) are taken up by the heart muscle. Although the general turnover rate of individual FFA has been studied, no investigations have been undertaken to discover their fate in the heart muscle. Aft...

Oils extracted from wild salmon by-products are excellent sources of long chain omega-3 polyunsaturated fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, quality loss is expected if time delays are encountered before oil extraction. The free fatty acid levels (FFA), fatty acid profile and total fat soluble antioxidant activity in extracted oil from aging...

Human platelets take up and metabobound FFA. These findings suggested Iize long-chain free fatty acids (FFA). that a large portion of the platelet FFA Experiments in which platelets were uptake might be associated with the loaded with ‘4C-palmitate, homogenplatelet surface. Radioautography with ized, and then fractionated indicated electron microscopy using 3H-palmilarge amounts of membrane-bou...
